BEARING PROTECTOR AND LUBRICATOR.

Specification of Letters Patent.

Application filed January 11, 1916. Serial No; 71,536.

To all whom it may concern Be it known that I, ARTHUR F. Poininn, a subject of the King of Great Britain, residing at Lewiston, in the county of Androscoggin and State of Maine, have invented certain new and useful Improvements in Bearing Protectors and Lubricators; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same,

This invention relates to a bearing protector and lubricator which is particularly adapted for use in connection with fabric carding machines, and the primary Ob ect of the invention is to provide a protecting housing for mounting over the open bearings of the working rolls and stripping rolls of a carding machine, so as to eliminate the accumulation of lint, dust, or the like about the shafts within the bearings, which accumulation of foreign matter tends to lift either the working rolls or stripping rolls so that they are not in the proper juxtaposition to each other for insuring the proper carding operation of the machine.

The protection of the bearings by the improved protector and lubricator, from lint, wool, or the like, enables the shaft to run free and true, and consequently necessitates the utilization of a minimum amount of power for the operation of the machine.

A further object of this invention is to provide a protecting housing as specified, which is constructed so that it will lubricate the bearing, and keep it cool for a relatively long period of time.

A further object of this invention is to provide a protecting and lubricating housing which is adaptable for attachment to any type of open bearing, which permits of the removal. of the shaft from the bearing, and which protecting housing may be quickly and easily attached to the shaft rotatable within the bearing and will not interfere either with the rotation of the shaft or the removal of the shaft from the bearing.

lVith the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed. x

In describing the invention in detail ref erence will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout the several views, and in which:

Figure 1 is a. side elevationof a bearing, showing the improved protecting and lubricating housing mounted thereon, Fig. 2 is a sectional view through the line 2-2 of Fig. 1, F 3 is a perspective view of the housing, Fig. at is an end view of a modified form of the protecting housing, and F ig. 5 is a view of the blank from which the housing is formed.

Referring more particularly to the drawing, 1 designates the shaft of a working or stripping roller of a fabric carding machine, which is rotatably supported by a bearing 2. The bearing 2 has the usual form of shank 3 thereon, by means of which it is attached to the supporting structure or frame of the carding machine. The bearing 2 is provided with an open socket a in which the shaft 1 V rotates.

The open socket permits lint, stringy wool or cotton and dust to accumulate therein and about the shaft 1, which decreases the effectiveness of the operation of the machine, in that. it raises the shaft 1 out of its proper bearing within the socket, which moves the working rolls and stripper rolls out of their proper relation with respect to each other.

The housing, generically indicated by the numeral 5. is provided for protecting the bearing of the shaft- 1 and to prevent the accumulation of foreign matter within the open socket a and about the shaft 1.

Thehousing 5, is constructed of a single piece of sheet metal, or, if desired, it may be cast and it comprises a cover plate 6, which has depending end plates 7 and 8 formed thereupon and also depending side plates 9 and 10. The end plates 7 and 8 are provided with openings 11 through which the shaft 1 extends. The end plates 7 and 8 and the side plates 9 and 10 are positioned so that their lower inner surfaces will engage the ends and sides of the bearing 2, as is clearly shown in Figs. 1 and 2 of the drawing, for forming a cover for the open end of the bearing or socket 4.

The housing 5 is mounted upon the shaft 1, at the outer end of the shaft, after the removal of the outermost collar 12, so that theinner side 8 of the housing engages the inner collar 18, which properly positions the housing over the portion of the shaft 1 which is rotatably mounted in the bearing 2. After the housing has been properly positioned, the collar 12 is remounted upon the shaft 1 and fastened thereto in the usual manner. The collars 12 and 13 prevent accidental longitudinal movement of the housing upon the shaft 1.

The cover plate 6 of the housing 5 is provided with an opening 14: extending therethrough, which is provided for permitting of the passage of lubricating oil through the cover plate to the felt pad 15, which is mounted interiorly of the housing and rests against the inner surface of the cover plate 6. When the felt pad 15 is saturated with lubricating oil, it will lubricate the bearing of the shaft 1 within the socket 4 and tend to keep the bearing cool for a. relatively long period of time, thereby eliminating the constant oiling or lubricating of the bearing. The felt pad 15 will also tend to prevent the accumulation of dust within the hearing.

In Fig. 4 of the drawings a modified form of the housing is shown, which housing is adapted for use upon carding machines, spindles, or analogous machines, wherein the supporting shaft of the working and stripping rolls are reduced in diameter at the portions which are mounted in the bearings. In such instances, the protecting housing 5 would not properly fit the shaft, and it is for the purpose of protecting bearings upon machines of this nature that the modified form is provided. This modified form comprises a housing 20. which is constructed of sheet metal, or may be cast if so desired, and has depending side plates 21 and depending end plates 22. The end plates 22 are provided with semicircular recesses 23 formed in their lower edges. Substantially U-shaped members '24 are pivotally connected to the end plates 22, as is shown at 25, and they are provided with semicircular or concaved portions 26, which are adapted for coaction with the recesses 23, when the U-shaped members 24; have both ends connected to the end 22 for forming an opening through which the shaft of the machine extends. The free end of the pivoted member 2-1 may be attached to the end 22 of the housing 20 in any suitable manner, such as by riveting or the like, and by varying the point of connection between the free end of thepivoted memher, and the end plate 22, the size of the opening formed by the recesses 23 and the concaved portion 26 may be regulated to accommodate shafts of various diameters In reducing the invention to practice certain minor features of construction, combihousing for said bearing, said housing 1ncluding a cover plate and depending side and end plates, said end plates being provided with openings for receiving said shaft for connecting the housing to the shaft, and lubricant retaining means positioned within said housing for lubricating said bearing.

3. The combination with a shaft, and an open bearing for the shaft, of a protecting housing for said bearing, said housing including a cover plate and depending side and end plates, said end plates being provided with openings for receiving said shaft for connecting the housing to the shaft, and means for varying the size of said shaft-receiving openings.

4. The combination with a shaft, and an open learing for the shaft, of a protecting housing removably carried by said shaft, said housing including a cover plate and depending side and end plates, said end plates provided with semicircular openings, substantially U-shaped members pivotally connected to said end plates for coaction with the semi-circular openings for forming shaft-receiving openings, and means for attaching the free ends of Said pivoted U-shaped members to the end plates.

The combination with a shaft, and an open bearing for the shaft, of a protecting housing removably carried by said shaft, said housing including a cover plate and depending side and end plates, said end plates provided with semi-circular openings. substantially U-shaped members pivotally connected to said end plates for coaction with the semi-circular openings for forming shaft receiving openings, means for attaching the free end of said pivoted U-shaped members to the end plate, and an absorbent lubricant retaining pad positioned within said housing.

In testimony whereof I affix my signature in presence of two witnesses.
